IJN has larger fleet size than Kriegsmarine.Kriegsmarine didn't have much ships since Hitler believed in U-Boat tactics and he ordered the navy to make more U-boats instead of making new ships.So the match depends on weather U-boats are allowed to Participate or Not.Without U-boats and Subs,IJN may win cause they have better Battleships and they are more in number.But if U-boats come in,the fate of the match may be different .
